Las Lagunas Gold Tailings is a retreatment project involving the reprocessing of previously unrecovered gold and silver refractory tailings from the Pueblo Viejo mine The project is situated 100km northwest of Santo Domingo the capital city of Dominican Republic in the Caribbean... As a leading global manufacturer of crushing equipment, milling equipment,dressing equipment,drying equipment and briquette equipment etc. we offer advanced, rational solutions for any size-reduction requirements, including quarry, aggregate, grinding production and complete plant plan.
Today the universal disposal method for tailings is the tailing pond Tailings are slurried with water and pumped to tailing ponds for settling Frequently tailings are cycloneclassified before deposition Coarse sands are used to buildup the tailing dam while the slimes are deposited inside the pond

Mineral Sands The grade from a typical mineral sand deposit is low – most ore deposits will have a total heavy mineral THM concentrate from the bulk sand of around 1 heavy minerals although some deposits can be significantly higher than this

Minerals processing is a broad term that includes a number of different processes and is as a whole one of the most important aspects of the overall mining operation Most mined materials from hardrock ores to solidfuel minerals such as coal oil shale and industrial minerals are subjected to some sort of size reduction andor other

Tailings consist of ground rock and process effluents that are generated in a mine processing plant Mechanical and chemical processes are used to extract the desired product from the run of the mine ore and produce a waste stream known as tailings This process of product extraction is never 100 efficient nor is it possible to reclaim all reusable and expended processing reagents and chemicals
